Question

what product by the action of chlorine on dry slaked lime and use reagent in the preparation of chloroform .who I am​

Answer 1

Answer:

When dry slaked lime reacts with chlorine, bleaching powder is produced. - Bleaching powder has the compound, calcium oxychloride having molecular formula, CaOCl2.

Answer 2

Answer:

When chlorine reacts with dry slaked lime which is calcium hydroxide Ca(OH)2 then the product formed is bleaching powder which is also used as a reagent in the preparation of chloroform.

Cl2 + Ca(OH)2 → CaOCl2 + CaCl2 + HCl

Here the mixture CaOCl2 is called the bleaching powder.

So the answer is Bleaching Powder.

                           

Explanation:

Let's first understand what is dry slaked lime ?

• Dry slaked lime is chemically known as calcium hydroxide and the formula for calcium hydroxide is Ca(OH)2.

Now when dry chlorine gas is passed through dry slaked lime which is calcium hydroxide Ca(OH)2 then a product is formed which is Calcium Oxychloride (CaOCl2) which is commonly known as bleaching powder.

Let's know more about Bleaching powder ,  

• Another name of bleaching powder is Calcium hypochlorite.
• The oxidation state of Calcium in bleaching powder is + 2
• It is also used in many industries.
• It is a yellowish white powder.

Here, in this whole reaction another product formed which is Calcium dichloride (CaCl2) which is an inorganic chloride.

• The procedure which is used here in the synthesis of bleaching powder is industrially used.

Now let's know more about some industrial uses of bleaching powder,

• It is a strong oxidizer
• It is a popular disinfectant to make potable water
• It is used to bleach wood pulp in paper industries

To obtain Bleaching Powder, the whole reaction must be carried out in dry conditions.

And the various undesirable products are formed in the reaction due to the presence of moisture.

Now let's understand How bleaching powder is also used in the preparation of chloroform ?

• Bleaching Powder is also used as a reagent in the preparation of chloroform.
• First of all bleaching powder (CaOCl2) reacts with water (H2O) to form chlorine and lime water which is Ca(OH)2.

                    CaOCl2 + H2O → Ca(OH)2 + Cl2  

• Then a paste of bleaching powder in water is distilled with acetone or ethanol to obtain chloroform.
• In this reaction bleaching powder act as a reagent.
